JPH04244905A - Method for inspecting appearance of carrier taping product - Google Patents

Abstract

PURPOSE:To enable an image to be taken stably with an image processing device in inspection of appearance of a carrier taping product using an image processing device. CONSTITUTION:A carrier taping product can be transported in vertical direction from a lower reel to an upper reel by rotating a sprocket and chip parts 9 are stuck to the bottom surfaces of embosses 10 and are in parallel with them due to the gravity within the embossess 10, thus enabling stable images to be taken in by an image processing device and preventing erroneous judgment.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for inspecting the appearance of carrier taped products, and more particularly to a method for inspecting the appearance of carrier taped products using an image processing device.

0002

2. Description of the Related Art A conventional method for inspecting the appearance of carrier taped products will be explained with reference to FIGS. 4 and 5.

Conventionally, as shown in FIG. 4, the appearance inspection method for carrier taped products involves rotating a sprocket 23 to move a carrier taped product 24 from one reel 21 to the other reel 22 in a horizontal direction (direction A in the figure). While feeding at a constant speed, the camera 25 synchronizes with the image of the external appearance of the chip component 29 housed in the embossment 30 of the carrier tape 28 as shown in FIG. was.

0004

[Problems to be Solved by the Invention] In the conventional visual inspection method for carrier taped products described above, the carrier taped products are fed in a horizontal direction, so that the chip components 29 are easily removed within the embossment 30 as shown in FIG. Since the image may move or be oriented diagonally, there is a problem in that the image processing device 26 cannot capture a stable image, resulting in erroneous determination.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for inspecting the appearance of carrier taped products, which enables stable image capture and prevents erroneous judgments.

[0006]

[Means for Solving the Problems] In order to achieve the above object, in a method for visually inspecting a carrier taped product according to the present invention, in a method for visually inspecting a carrier taped chip component using an image processing device, the carrier tape is The appearance of chip components is inspected while being fed vertically or diagonally.

[0007]

[Operation] The present invention realizes stable image capture by inspecting the appearance of chip parts while feeding the carrier tape upward in a method of visually inspecting carrier-taped chip parts using an image processing device. It is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

(Embodiment 1) FIG. 1 is a block diagram showing an appearance inspection system for carrier taped products according to Embodiment 1 of the present invention. In the figure, carrier taping product 4 is
By rotating the sprocket 3 from the lower reel 1 to the upper reel 2, it is sent along the guide 7 in the vertical direction (direction A in the figure) at a constant speed. A camera 5 is disposed parallel to the guide 7 of such a carrier taping product feeding mechanism at a certain distance, and the chip component 9 housed in the embossment 10 of the carrier tape 8 as shown in FIG. 2 is synchronized with the camera 5. The appearance of the image is taken, and the image is judged by the image processing device 6 as to whether it is good or bad.

In this embodiment, as shown in FIG.
Because they are in close contact with the inner lower surface, the orientation of each chip component is parallel.

(Embodiment 2) FIG. 3 is a block diagram showing Embodiment 2 of the present invention. In this embodiment, the carrier tape 8 is fed at a certain angle θ from the vertical direction, and the chip components 9 within the embossment 10 are
Since it is in close contact with not only the inner lower surface but also the side surface, there is an advantage that positioning can be performed in the vertical and horizontal directions at the same time.

0012

[Effects of the Invention] As explained above, in the present invention, the carrier taped product is fed vertically or diagonally, so the chip parts in the embossment are parallel, so the image processing device can always capture stable images. This has the effect of eliminating judgment.
